Hi, One of proxies died down today, because the log files were overwhelming: -rw-r----- 1 squid squid 61440 Aug 17 16:01 access.log -rw-r----- 1 squid squid 523366451 Aug 17 02:59 access.log.0 -rw-r----- 1 squid squid 771658231 Aug 17 00:00 access.log.1 -rw-r----- 1 squid squid 562853886 Aug 16 21:00 access.log.2 -rw-r----- 1 squid squid 618221433 Aug 16 18:00 access.log.3 -rw-r----- 1 squid squid 572403480 Aug 16 15:00 access.log.4 -rw-r----- 1 squid squid 379977665 Aug 16 12:00 access.log.5 -rw-r----- 1 squid squid 348474013 Aug 16 09:00 access.log.6 -rw-r----- 1 squid squid 367307983 Aug 16 06:00 access.log.7 -rw-r----- 1 squid squid 663904388 Aug 16 03:00 access.log.8 -rw-r----- 1 squid squid 735110835 Aug 16 00:00 access.log.9 -rw-r----- 1 squid squid 36715761664 Aug 17 16:01 cache.log -rw-r----- 1 squid squid 14262776941 Aug 17 03:00 cache.log.0 -rw-r----- 1 squid squid 955445 Aug 17 00:00 cache.log.1 -rw-r----- 1 squid squid 748262 Aug 16 21:00 cache.log.2 -rw-r----- 1 squid squid 1069482 Aug 16 18:00 cache.log.3 -rw-r----- 1 squid squid 698758 Aug 16 15:00 cache.log.4 -rw-r----- 1 squid squid 497547 Aug 16 11:59 cache.log.5 -rw-r----- 1 squid squid 271153 Aug 16 08:59 cache.log.6 -rw-r----- 1 squid squid 355351 Aug 16 05:59 cache.log.7 -rw-r----- 1 squid squid 759748 Aug 16 02:59 cache.log.8 -rw-r----- 1 squid squid 1037802 Aug 15 23:59 cache.log.9 As you can see, those "HUGE" cache log files were filled up in less than 12 hours. Opening them up, I find they were filled with the following lines, repeated over and over again: 2010/08/17 02:33:11| comm_accept: FD 28: (22) Invalid argument 2010/08/17 02:33:11| httpAccept: FD 28: accept failure: (22) Invalid argument 2010/08/17 02:33:11| comm_accept: FD 28: (22) Invalid argument 2010/08/17 02:33:11| httpAccept: FD 28: accept failure: (22) Invalid argument 2010/08/17 02:33:11| comm_accept: FD 28: (22) Invalid argument 2010/08/17 02:33:11| httpAccept: FD 28: accept failure: (22) Invalid argument And, that is the time from when it started. Is there any way to determine what is causing this? Regards HASSAN
