--- Comment #2 from [email protected] --- We experience semaphore collisions too when there a many apache instances on a machine. Apache tries to create a semaphore which is already occupied by another users apache instance. If I interpret the code correctly the username prefix for the ID won't work because the ID is passed to shmget, and key_t is an integer. So various data is passed to a hash function to create a unique key_t. To me it seems it's not so unique and collisions are more likely than intended? Isn't it possible to use IPC_PRIVATE? For quick lookup: AH01179 happens here in line 797: http://svn.apache.org/viewvc/httpd/httpd/tags/2.4.6/modules/proxy/mod_proxy_balancer.c?revision=1503324&view=markup conf->id is some hashed value of some data created in line 766, and is presumably passed as key_t to shmget at the end. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
