The problem here is that there is some sort of leand in the slabcache. Specifically iy appears that the names_cache it consuming all of lowmem which results in an OOM kill. Please get me an entire /proc/slabinfo output when the OOM kill occurs. Please attach that output as well as the show_mem() output that appears on the console when the OOM kill occurs. BTW, is this a regression from RHEL4-U1 or did the same problem happen when you ran this application/test on that kernel? Larry Woodman Let me re-write me last comment im "english" !!!
