Hello, On our 10-stable boxes sometimes processes crash with the following errors: Failed to write core file for process check_ssh (error 14) pid 81441 (check_ssh), uid 181: exited on signal 11 Failed to write core file for process nagios (error 14) pid 30255 (nagios), uid 181: exited on signal 11 Failed to write core file for process sh (error 14) pid 59267 (sh), uid 181: exited on signal 11 Failed to write core file for process nagios (error 14) pid 99102 (nagios), uid 181: exited on signal 11 gdb does not show stack: (gdb) bt #0 0x0000000800bffb9b in ?? () Cannot access memory at address 0x7fffffffd588 It started several months ago after OS update to fresh 10/stable (but I do not remember details: which version were before and from which version that started). Does anyone observe something similar? Thanks.

I've rebuilt it with experimental options off and it stopped segfaulting.
