I see pretty much the same problem when running the test suite against localhost; the locking test blocks in fcntl() when it shouldn't be. 89182 tlock 0.000507 RET write 44/0x2c 89182 tlock 0.000071 CALL fcntl(0x7,0x7,0xbfbff680) 89182 tlock 0.000025 NAMI "/var/run/lock" 89183 tlock 1.568295 RET read RESTART 89182 tlock 0.000152 RET fcntl RESTART #define F_GETLK 7 /* get record locking information */ It looks like something is wrong with file locking.
