After a restart of Squid today, I found the following in the cache.log: 2005/03/02 09:13:22| Starting Squid Cache version 2.5.STABLE7 for i686-pc-linux-gnu... 2005/03/02 09:13:22| Process ID 15980 2005/03/02 09:13:22| With 16384 file descriptors available 2005/03/02 09:13:22| DNS Socket created at 0.0.0.0, port 32775, FD 4 2005/03/02 09:13:22| Adding nameserver XXX.XXX.XXX.XXX from squid.conf 2005/03/02 09:13:22| Unlinkd pipe opened on FD 9 2005/03/02 09:13:22| Swap maxSize 15564800 KB, estimated 1197292 objects 2005/03/02 09:13:22| Target number of buckets: 59864 2005/03/02 09:13:22| Using 65536 Store buckets 2005/03/02 09:13:22| Max Mem size: 65536 KB 2005/03/02 09:13:22| Max Swap size: 15564800 KB 2005/03/02 09:13:22| Store logging disabled 2005/03/02 09:13:22| Rebuilding COSS storage in /opt/squid-master/var/cache/coss0 (CLEAN) 2005/03/02 09:13:22| Rebuilding COSS storage in /opt/squid-master/var/cache/coss1 (CLEAN) 2005/03/02 09:13:22| Rebuilding COSS storage in /opt/squid-master/var/cache/coss2 (CLEAN) 2005/03/02 09:13:22| Rebuilding COSS storage in /opt/squid-master/var/cache/coss3 (CLEAN) 2005/03/02 09:13:22| Rebuilding COSS storage in /opt/squid-master/var/cache/coss4 (CLEAN) 2005/03/02 09:13:22| Rebuilding COSS storage in /opt/squid-master/var/cache/coss5 (CLEAN) 2005/03/02 09:13:22| Rebuilding COSS storage in /opt/squid-master/var/cache/coss6 (CLEAN) 2005/03/02 09:13:22| Rebuilding COSS storage in /opt/squid-master/var/cache/coss7 (CLEAN) 2005/03/02 09:13:22| Using Least Load store dir selection 2005/03/02 09:13:22| Set Current Directory to /opt/squid-master/var/core 2005/03/02 09:13:22| Loaded Icons. 2005/03/02 09:13:22| Accepting HTTP connections at 0.0.0.0, port 8080, FD 32. 2005/03/02 09:13:22| Ready to serve requests. 2005/03/02 09:13:22| assertion failed: cbdata.c:163: "type > 0 && type < cbdata_types" 2005/03/02 09:13:25| Starting Squid Cache version 2.5.STABLE7 for i686-pc-linux-gnu... 2005/03/02 09:13:25| Process ID 15983 2005/03/02 09:13:25| With 16384 file descriptors available 2005/03/02 09:13:25| DNS Socket created at 0.0.0.0, port 32775, FD 4 2005/03/02 09:13:25| Adding nameserver 159.46.248.2 from squid.conf 2005/03/02 09:13:25| Unlinkd pipe opened on FD 9 2005/03/02 09:13:25| Swap maxSize 15564800 KB, estimated 1197292 objects 2005/03/02 09:13:25| Target number of buckets: 59864 2005/03/02 09:13:25| Using 65536 Store buckets 2005/03/02 09:13:25| Max Mem size: 65536 KB 2005/03/02 09:13:25| Max Swap size: 15564800 KB 2005/03/02 09:13:25| Store logging disabled 2005/03/02 09:13:25| Rebuilding COSS storage in /opt/squid-master/var/cache/coss0 (DIRTY) 2005/03/02 09:13:25| Rebuilding COSS storage in /opt/squid-master/var/cache/coss1 (DIRTY) 2005/03/02 09:13:25| Rebuilding COSS storage in /opt/squid-master/var/cache/coss2 (DIRTY) 2005/03/02 09:13:25| Rebuilding COSS storage in /opt/squid-master/var/cache/coss3 (DIRTY) 2005/03/02 09:13:25| Rebuilding COSS storage in /opt/squid-master/var/cache/coss4 (DIRTY) 2005/03/02 09:13:25| Rebuilding COSS storage in /opt/squid-master/var/cache/coss5 (DIRTY) 2005/03/02 09:13:25| Rebuilding COSS storage in /opt/squid-master/var/cache/coss6 (DIRTY) 2005/03/02 09:13:25| Rebuilding COSS storage in /opt/squid-master/var/cache/coss7 (DIRTY) 2005/03/02 09:13:25| Using Least Load store dir selection 2005/03/02 09:13:25| Set Current Directory to /opt/squid-master/var/core 2005/03/02 09:13:25| Loaded Icons. 2005/03/02 09:13:25| Accepting HTTP connections at 0.0.0.0, port 8080, FD 24. 2005/03/02 09:13:25| Ready to serve requests. 2005/03/02 09:13:25| Finished rebuilding storage from disk. 2005/03/02 09:13:25| 0 Entries scanned 2005/03/02 09:13:25| 0 Invalid entries. 2005/03/02 09:13:25| 0 With invalid flags. 2005/03/02 09:13:25| 0 Objects loaded. 2005/03/02 09:13:25| 0 Objects expired. 2005/03/02 09:13:25| 0 Objects cancelled. 2005/03/02 09:13:25| 0 Duplicate URLs purged. 2005/03/02 09:13:25| 0 Swapfile clashes avoided. 2005/03/02 09:13:25| Took 0.0 seconds ( 0.0 objects/sec). 2005/03/02 09:13:25| Beginning Validation Procedure 2005/03/02 09:13:26| Completed Validation Procedure 2005/03/02 09:13:26| Validated 0 Entries 2005/03/02 09:13:26| store_swap_size = 0k 2005/03/02 09:13:26| storeLateRelease: released 0 objects I haven't been able to find anything on the 'assert failed' line, which seems to have caused the cache to be wiped clean. Is this a known problem? If it isn't, this is the first time I see this problem in the few months this machine has been running, so I don't know if I can produce a stack trace .... (currently core-size is set to 0, so there's no coredump for this problem) Joost
