Hi Bjoern,

thanks a lot for reporting this issue - it looks like there are some problems in the cleanup of OGMs when fragmentation is used.

For now, I've created a ticket here:

https://www.open-mesh.org/issues/223

Thanks, Simon

Unfornately we have no logs now, because after the crashes no ssh -access to the servers are possible.

try to set

/sbin/sysctl -w kernel.panic_on_oops=1 /sbin/sysctl -w kernel.panic=10 /sbin/sysctl -w vm.panic_on_oom=2

if the devices crashed (and reboots now) you have the crash in the file:

/sys/kernel/debug/crashlog

Thanks for the hint, it did not work on the debian machines, but I got the systems running with crashkernel enabled. Now we got the first crash: https://p.rrbone.net/paste/nnNHrIJI#oHfBMOs2
