[ILUG] [OT] Looking for recommendations for solaris memory checker

[Paul Jakma]

Ah, more mdb/libumem tips:

::findleaks will show you who allocated the memory, but that
mightn't be very helpful. Luckily, libumem records a stack trace at 
each allocation, use BUFFER$<bufctl_audit to print that out.

Eg, to display the top 5 'leakers' and look at stack traces for them:

> ::findleaks ! sort -k 2 -n | tail -5
000c4c88      12 00284ca8 myallocator+4
000c4508      15 003b4708 myallocator+4
000c4508     869 003ea5a0 myallocator+4
000c4508     885 003b4780 myallocator+4

> 003b4780$<bufctl_audit

<lots of useful info, including thread id, last alloc + the important 
stack trace of call path leading to the allocation..>
