Despite the fact I have Strigi disabled and that I have configured it to ignore external disks, every time my script runs nepomukservices goes CPU crazy (especially when I delete an old backup) and about one time in 3 it crashes like this. The crash can be reproduced some of the time. -- Backtrace: Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted __lll_lock_wait_private () at ../nptl/sysdeps/unix/sysv/linux/x86_64/lowlevellock.S:97 in ../nptl/sysdeps/unix/sysv/linux/x86_64/lowlevellock.S [Current thread is 1 (Thread 0x7fa8c41b6780 (LWP 2245))] Thread 24 (Thread 0x7fa8b002b700 (LWP 2396)): #0 __lll_lock_wait_private () at ../nptl/sysdeps/unix/sysv/linux/x86_64/lowlevellock.S:97 #1 0x00007fa8c182980f in _L_lock_12013 () from /lib/x86_64-linux-gnu/libc.so.6 #2 0x00007fa8c18278d8 in __libc_free (mem=0x7fa8c1b3a1c0) at malloc.c:3736 #3 0x00007fa8c0ab39b4 in ??

Committed on 17/10/2011 at 11:12. Pushed by trueg into branch 'master'. Protect the prefix map with a mutex.

Soprano::NRLModel::executeQuery() attempts to lock the m_prefixMapMutex mutex, but it has already been locked in buildPrefixMap(). If the mutex is needed in both these places then it needs to be a recursive mutex. The attached patch implements this - the mutex recursion mode can only be set during initialisation, so it needs to be changed to an explicitly allocated pointer. 1175616 4 64740 jjm 2011-10-20 20:11:56 +0000 Created attachment 64740 Patch to fix as per comment #3 1175694 5 trueg 2011-10-21 07:59:55 +0000 Git commit ae0050b3b63e510c15e23d7da410736489dc4b30 by Sebastian Trueg.
