Hi, sorry that i posted it here. after some time i realised that the reverse proxy is IHS ibm http server and not pure apache httpd. anyway i post my findings here. after switching from mem caching to disk caching the issue disappeared.

Everything is working fine but after a few days the reverse proxy starts to send all the requests to the backend server. Is there a way to see what objects are cached in mem? Or should i switch to disk cache to see that?
