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.
