Hi, Im running varnish with 3 load balance directors. The first again two windows IIS and the second against a couple of Apache servers, and the third against a couple of Glassfish Servers. The Apache and Glassfish are on the same machines.
Yesterday Varnish staterd to behavie erractil, the sites stop responding and i had to restart varnish every 5 minutes for make it work again. I saw this in the log, i dont know exactly what it means: ######################################################## 147 TxRequest b GET 147 TxURL b /fcgi-bin/mapserv?map=/var/www/mapcity_2_0/map/chile_tiled.map&LAYERS=Oceano%2Craster_sudamerica%2CBoundaries%2CPark%2Curban%2CElevation%2CLakes%2CHidrography%2CEscaleras%2CCalles%2CAvenidas%2CAutopistas%2CCaminos%2Camerica%2Cbound_limit%2CLocality&FORMAT 147 TxProtocol b HTTP/1.1 147 TxHeader b Accept: */* 147 TxHeader b Referer: http://192.168.1.15:8080/cache/ 147 TxHeader b Accept-Language: es-cl 147 TxHeader b UA-CPU: x86 147 TxHeader b Accept-Encoding: gzip, deflate 147 TxHeader b User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; WOW64; SLCC1; .NET CLR 2.0.50727; .NET CLR 3.0.04506; InfoPath.2) 147 TxHeader b Host: mapa4.mapcity.com 147 TxHeader b X-Forwarded-For: 172.16.1.20 147 TxHeader b X-Varnish: 1045402604 147 TxHeader b X-Forwarded-For: 172.16.1.20 173 SessionClose c dropped 173 StatSess c (null) (null) 1226247930 0 0 0 0 0 0 0 231 SessionClose c dropped 231 StatSess c (null) (null) 1226247930 0 0 0 0 0 0 0 234 SessionClose c dropped 234 StatSess c (null) (null) 1226247930 0 0 0 0 0 0 0 235 SessionClose c dropped 235 StatSess c (null) (null) 1226247930 0 0 0 0 0 0 0 236 SessionClose c dropped 236 StatSess c (null) (null) 1226247930 0 0 0 0 0 0 0 236 SessionClose c dropped 236 StatSess c (null) (null) 1226247931 0 0 0 0 0 0 0 237 SessionClose c dropped 237 StatSess c (null) (null) 1226247931 0 0 0 0 0 0 0 238 SessionClose c dropped 238 StatSess c (null) (null) 1226247931 0 0 0 0 0 0 0 ################################################################## The lines with "SessionClose c dropper and null..." start repeating until i restarted Varnish.
