Greetings,
I'm running linux and Boinc 7.0.27
I noticed a segfault in my system log (kern.log.1) and syslog :
[369168.751849] wcgrid_cep2_qch[22385]: segfault at 5d0b7000 ip 000000000d8edea4 sp 00000000ff9c1194 error 4 in wcgrid_cep2_qchem_6.40_i686-pc-linux-gnu[8048000+6297000]

I did not see anything unusual in the BOINC event log.

I don't think I'm overloading with too many tasks.
I'm running on 7 of 8 cores (87.5%) anly am configured to run only one CEP2 wu at a time.

Question: Where do I start debugging?

FYI - env. stuff:

I'm trying to link a result reported with the wu that was in progress.
I think this is the one it finished 4 hours after the segfault.:
Link to WCG results

Or, should I just ignore??

T H A N K Y O U!!
