Hello Everyone , I am runing CentOS 5 with ipvsadm v1.24 2003/06/07 (compiled with popt and IPVS v1.2.0) which is pushing ~10mbit and unfortunatelly I am having serious issues with the machine after ~24hrs it freezes and OOM issues appear .
In stock running kernel 2.6.18-8.el5 . Does anyone have any ideea if this is an issue within the ipvs code or something else ? Slabtop shows this : Active / Total Objects (% used) : 1071145 / 1141936 (93.8%) Active / Total Slabs (% used) : 189599 / 189599 (100.0%) Active / Total Caches (% used) : 93 / 141 (66.0%) Active / Total Size (% used) : 745844.78K / 753778.20K (98.9%) Minimum / Average / Maximum Object : 0.01K / 0.66K / 128.00K OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME 347362 347309 99% 0.03K 3074 113 12296K size-32 346044 346044 100% 2.00K 173022 2 692088K size-2048 174168 174168 100% 0.06K 2952 59 11808K size-64 126990 99513 78% 0.12K 4233 30 16932K ip_vs_conn 56952 30763 54% 0.05K 791 72 3164K buffer_head Personally I suspect a memory leak within ipvs code.
