Ok, I am having a time of my life here. My squid service is still crashing and restarting. I am unable to get a core dump. However, I have found that everytime it happens, I get the error: Jun 16 17:40:56 xxxxx squid[6509]: storeDirWriteCleanLogs: Starting... Jun 16 17:40:56 xxxxx squid[6509]: WARNING: Closing open FD 16 Jun 16 17:40:56 xxxxx squid[6509]: Finished. Wrote 0 entries. Jun 16 17:40:56 xxxxx squid[6509]: Took 0.0 seconds ( 0.0 entries/sec). I have also found that everytime either during the second that it crashes or the second right before it crashes, a known spyware site has been tried to be accessed. I receive a TCP_Denied, so I know it is not getting out to the site, but it still seems to be the culprit that is causing my cache to die. Typically, the site looks somewhat like this: "172.20.33.18":;"-":;"172.18.10.200":;1118958055:;2005-06-16 17:40:55:830:;0:;"-":;"-":;"407":;"GET":;"http://www.frankfurter-buchmes se.de/o.php":;"1.0":;2385:;"text/html":;"TCP_DENIED" Also, if I run "free -m" on my system, I get the following: otal used free shared buffers cached Mem: 1007 992 14 0 79 794 -/+ buffers/cache: 118 888 Swap: 996 9 986 Does anyone know what may be the cause of this? Is there a way I can get a definitive answer on what is crashing my service (the box stays up and responsive, just restarts the service from the RunCache)? I'm really pulling my hair out here, and upper management is breathing down my neck.... Thanks Sam
