SYMPTOM(s):
Connecting with sqlexp
Error: [JDBC Progress Driver]:No Data. (8933)
sql engine thread creation failed (11)
CAUSE:
Bug#: 20020517-035
CAUSE:
The system call error 11 means "Resource temporarily unavailable". Sometimes, it happens due to out of available file descriptors. It can also be due to being out of available mutexes.
FIX:
1. Upgrade to Progress 10.0A
Improved our function to start a thread by passing the logfile object and reporting the error to the logfile from within the function. You will still see error numbers such as 11 reported as the threading functions return this code for a variety of reasons. Diagnosis of the actual root cause will require knowledge of system resource limit settings.
2. Investigate operating system resource limitations.
