Created attachment 5516 [details] This is the dump analysis taken after observing OOps Andrew I was able to replicate it following same process[killing vmmstress] I am attaching the Preliminary analysis of the dump. It seems to be the problem with mm/mmap.c line 1962. I couldn't exactly figure out the cause for the OOPs
Is this fixed?
I looked into 2.6.15-rc7 but the problem was not observed. I am looking into it will update later.
Sharyathi, what is the status of this issue in kernel 2.6.16?
Please reopen this bug if it's still present in kernel 2.6.17.
