Thanks for the thoughts Chris, but I found the cause. I had lowered the the keepalivetimeout setting to 10s because our application polls in 2.5s intervals, pretty unexpected result (I figured 10s should be enough).
I think the connection gets closed somewhere in the middle of the post request but the request is still accepted as complete. The post parameters are never received and/or processed. Raising keepalivetimeout on the apr connector from 10s to 60s drastically lowered the amount of occurences. (on par with the amount we had on other servers with NIO where the keepalivetimeout defaulted to 60s, we always had this issue but to a much lower extent) It occurred to me after reading this: http://mail-archives.apache.org/mod_mbox/tomcat-users/200708.mbox/%3c46d6f4a6.1000...@mbuyu.nl%3e --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
