With the shm cache in the 1.3 releases, the shm_user and shm_group *must* be set to the user/group running apache, otherwise it's likely that a graceful restart will not be successful and cause apache to hang. You'll also see messages in the error log such as [Mon May 20 09:26:47 2002] [warn-phpa] release_shm_cache failed to delete - Operation not permitted (pid 20514) [Mon May 20 09:26:47 2002] [warn-phpa] Failed to remove sems - Operation not permitted (pid 20514) The user/group names are whatever are specified for user and group in the httpd.conf ------------------------------------------------------------------------ www.php-accelerator.co.uk Home of the free PHP Accelerator To post, send email to phpa@xxxxxxxxxxxxx To unsubscribe, email phpa-request@xxxxxxxxxxxxx with subject unsubscribe
