Large "slabcache" Size due to Growing Size of "anon_vma_chain"
(Doc ID 1637807.1)
Last updated on OCTOBER 25, 2020
Applies to:
Linux OS - Version Oracle Linux 5.5 with Unbreakable Enterprise Kernel [2.6.32] and laterOracle Cloud Infrastructure - Version N/A and later
x86 32 bit
x86 64 bit
Symptoms
- The slab cache size as reported by "meminfo"may be very large size. For example:
- And the size of the slab object "anon_vma_chain" is very large as observed with "cat /proc/slabinfo" or under the slabtop(1) command.
- On a 32-bit system, one might notice that the low memory gets quickly depleted because of this reason and that the system invokes "Out Of Memory Killer" attempting to reclaim memory.
Changes
The problem starts to appear after starting some application that would create child processes in a continuous loop.
