Hi, I'm looking at implementing varnish 2.0.5 as a front end to our apache web servers to cache static files. I'm currently testing and having issues with backend connections. Since this is a test system, it is not heavily used. I notice that if it goes without any requests for some time (over an hour or so), the next request received goes through the cycle below of 'FetchError c no backend connection' and restart until it hits the restart limit of 6. It also seems that if requests occur every few minutes that this is not an issue, so I suspect a timeout of some kind.
I've been searching and reading but have not found an explanation for this behavior yet. More complete log of this can be seen at http://www.manta.com/jah/varnish_log.txt The command line I'm using to run varnish can be seen at http://www.manta.com/jah/varnish_start.txt Current vcl can be seen at http://www.manta.com/jah/varnish_vcl.txt I'd appreciate any insight. Thanks, Jim Varnish_log.txt excerpt: 4 VCL_call c recv 4 VCL_return c pass 4 VCL_call c pass 4 VCL_return c pass 31 BackendClose b default 5 BackendClose b default 4 FetchError c no backend connection 4 VCL_call c error 4 VCL_return c restart 4 VCL_call c recv 4 VCL_return c pass 4 VCL_call c pass 4 VCL_return c pass 4 FetchError c no backend connection 4 VCL_call c error 4 VCL_return c restart 4 VCL_call c recv 4 VCL_return c pass 4 VCL_call c pass 4 VCL_return c pass 4 FetchError c no backend connection 4 VCL_call c error 4 VCL_return c restart 4 VCL_call c recv 4 VCL_return c pass 4 VCL_call c pass 4 VCL_return c pass 4 FetchError c no backend connection 4 VCL_call c error 4 VCL_return c restart 4 VCL_call c recv 4 VCL_return c pass 4 VCL_call c pass 4 VCL_return c pass 4 FetchError c no backend connection 4 VCL_call c error 4 VCL_return c restart 4 VCL_call c recv 4 VCL_return c pass 4 VCL_call c pass 4 VCL_return c pass 4 FetchError c no backend connection 4 VCL_call c error 4 VCL_return c restart 4 VCL_call c recv 4 VCL_return c pass 4 VCL_call c error 4 VCL_return c deliver 4 Length c 488 4 VCL_call c deliver 4 VCL_return c deliver 4 TxProtocol c HTTP/1.1 4 TxStatus c 503 4 TxResponse c Service Unavailable 4 TxHeader c Server: Varnish 4 TxHeader c Retry-After: 0 4 TxHeader c Content-Type: text/html; charset=utf-8 4 TxHeader c Content-Length: 488 4 TxHeader c Date: Tue, 08 Dec 2009 21:37:50 GMT 4 TxHeader c X-Varnish: 1690688575 4 TxHeader c Age: 0 4 TxHeader c Via: 1.1 varnish 4 TxHeader c Connection: close 4 TxHeader c X-Served-By: ecnext39 4 TxHeader c X-Cache: MISS 4 ReqEnd c 1690688575 1260308270.019510984 1260308270.020113707 0.004284143 0.000570059 0.000032663 4 SessionClose c error 4 StatSess c 66.104.100.163 61534 0 1 1 0 6 0 273 488 _______________________________________________ varnish-misc mailing list varnish-misc@projects.linpro.no http://projects.linpro.no/mailman/listinfo/varnish-misc
