Suspected memory leak in PCU

Hi all,

while running osmo-pcu, it appears that it is leaking memory. At startup time it consumes 4188 kBytes of virtual memory (on sysmobts-v2), while after about 8MBytes of data transfer of a single GPRS-MS over 48 hours, the virtual size has expanded to 8584 kBytes.

Now I know that VSS is not RSS, etc. - but the fact that it always only increasees, and increases with traffic is a clear indication of some leakage somewehere.

Unfortunately it also seems talloc is not used correctly in osmo-pcu, as a USR1 signal doesn't really show any allocated objects beyond two. So somehow either not all allocations are done with talloc, or the allocation hierarchy does not link the objects to the root talloc context.

Regards, Harald
