Dear all,
while using tntnet I have trouble with the poller thread.
It throws the following error message:
Error message
-----------
exception occured: pthread_mutex_unlock: errno 1: Operation not permitted
-----------
When connecting with 5-10 clients, the error appears for example after
50 minutes. The website itself is an ajax based website with reload
interval of 1s.
Does anyone have similar problems?
Best regards,
Sven
Below please find an strace snippet:
