Problem IT42320 | Status: Closed |
MISSING OR INVALID OS LOCALE INFORMATION MAY LEAD TO ASSERT FAILURE OR INSTANCE HANG DURING KAIO THREAD START UP. | |
product: | |
INFORMIX SERVER / 5725A3900 / E10 - | |
Problem description: | |
The initialization of a KAIO thread may involve printing messages to the online log. When the MSG_DATE onconfig parameter is 1 the date + time part of that message will be formatted according to the OS locale. If such locale information is not present then the KAIO thread may raise an Assert Failure and this may lead to a hang of the instance without any information being written to the online log file. Using a command such as "onstat -g act" will show one kaio thread running continuously on the same VP and this may include other threads in a continuous run state. Using an OS utility to dump the stack for the VP will show the stack to be similar to: mt_spin_lock_wait () mt_sysmsg_body () afhandler () afcrash_interface () mt_ex_throw_sig () afsig_handler () 0x0000000000000000 in ?? () gl_mbsftime1 () gl_mbsftime () mt_sysmsg_body () mt_logvprintf () mt_logprintf () _aioinit () kaiothread () startup () | |
