Hello,
I have a Python script that writes messages to syslog.
The script works with the print and sleep commands. When I remove the
print and sleep commands, only the first two commands appear in
local5.log file.
Well I think the problem is in the fast repetition of openlog +
closelog. The messages may be buffered or discarded by some rate
limiting. If you remove syslog.closelog() from the LOG_E function and
put it at the end of the script, all messages are logged, because syslog
receive them in one connection.
