Subject: [2.6.7, ia64] continual memory leak at ~102kB/s...
Date: Fri, 06 Aug 2004 14:44:18 +0000 [thread overview]
Message-ID: <20029.1091803458@www55.gmx.net> (raw)
When running 2.6.7 on a generic ia64 system, I see memory being leaked in
the kernel. Most of the fancy (preempt, hot-plug procs, ...) features are
disabled, and the system in a quiescent state [1].
/proc/meminfo shows the memory as unaccounted for [2], so it seems likely it
has been kmalloc()d somehere. A small script shows memory disappearing at
102kB/s [3].
Anyone else seen this on ia64?
