Hi, I am running squid-2.6.Stable 3 on linux-2.6.10 kernel I am using squid epoll and coss cache_dir. System memory: 4 GB Cache Memory: 2 GB cache_dir coss /cache01/coss 10000 block-size=2048 max-size=131072 cache_dir coss /cache02/coss 10000 block-size=2048 max-size=131072 I am getting the below error message. storeCossCreateMemOnlyBuf: no free membufs. You may need to increase the value of membufs on the /cache01/coss cache_dir Do i require to change any configuration in squid? Regards Chima
