Hello, I have running Squid Cache: Version 3.0.STABLE13 with ntlm auth, using samba-3.2.10 and winbind, also SquidGuard 1.4 Since a few days I am detecting that squid is going down (then restart again without any problem) with the error: 2009/05/06 12:59:33| assertion failed: comm.cc:572: "fdc_table[fd].active == 1" [2009/05/06 12:59:34, 1] utils/ntlm_auth.c:manage_squid_request(2167) fgets() failed! dying..... errno=1 (Operation not permitted) I really don't know what`s going wrong. It usually occurs when I do a squid reload. If you need more information please say to me. The complete cache.log of the error is: 2009/05/06 12:59:16| storeDirWriteCleanLogs: Starting... 2009/05/06 12:59:16| 65536 entries written so far. ... 2009/05/06 12:59:17| 1245184 entries written so far. 2009/05/06 12:59:17| Finished.
