64 bit rhel5 60.2, 2 32 bit VE's 8GB of ram without swap
what is filp cache ?
Am i right that it was 4,9GB big ?
Mar 29 15:49:11 hd1 kernel: filp : size 4979023872 objsize 256
it looked like some memory leak (for 6 hours memory usage was raising) 2 VE's have total 6GB privvmpages + 4,9GB for flip cache makes it possible.
