We've gotten our servers upgraded to 64-bit OS, and seen tremendous stability enhancement with varnish over our 32-bit os, which crashed every 5-10 minutes. We can now get about 2 days of uptime before we have a new child process crash. Logs are listed below.. Wondering if something obvious jumps out at anyone as to what the cause of this may be.<div><br></div><div>Appreciate any insight from the community ! </div><div><br></div><div><div>Sep 30 16:37:17 srv860 varnishd[16195]: Child (16196) died signal=6</div><div><br></div><div>Sep 30 16:37:17 srv860 varnishd[16195]: Child (16196) Panic message: Assert error in WS_Release(), cache_ws.c line 193: Condition(bytes <= ws->e - ws->f) not true. errno = 104 (Connection reset by peer) thread = (cache-worker) ident = Linux,2.6.18-194.el5,x86_64,-smalloc,-hcritbit,epoll Backtrace: 0x422616: /usr/sbin/varnishd [0x422616] 0x42d475: /usr/sbin/varnishd(WS_Release+0xf5) [0x42d475] 0x427b33: /usr/sbin/varnishd [0x427b33] 0x42bc45: /usr/sbin/varnishd(VRT_SetHdr+0xf5) [0x42bc45] 0x2aaaab003e76: ./vcl.1P9zoqAU.so [0x2aaaab003e76] 0x427006: /usr/sbin/varnishd(VCL_deliver_method+0x46) [0x427006] 0x4130cf: /usr/sbin/varnishd [0x4130cf] 0x413e49: /usr/sbin/varnishd(CNT_Session+0x369) [0x413e49] 0x424a68: /usr/sbin/varnishd [0x424a68] 0x423d4d: /usr/sbin/varnishd [0x423d4d] sp = 0x2aaac060e008 { fd = 351, id = 351, xid = 1104824170, client = 63.240.230.197:26479, step = STP_DELIVER, handling = deliver, restarts = 0, esis = 0 ws = 0x2aaac060e078 { id = "sess", {s,f</div><div><br></div><div>Sep 30 16:37:17 srv860 varnishd[16195]: child (32562) Started</div><div><br></div><div>Sep 30 16:37:17 srv860 varnishd[16195]: Child (32562) said </div><div><br></div><div>Sep 30 16:37:17 srv860 varnishd[16195]: Child (32562) said Child starts</div></div></body></html>
