nsclient++ crashing

Hi all,
 
A little while ago there was a thread on this mail list regarding the
stability of nsclient++ on Windows 2003, at the time I had not
encountered this issue. Now that I have deployed nsclient++ to >200
Servers I am seeing one or two crashes a day. I do not use passwords,
nor encryption. I am using a combination of ns_client and nrpe checks
until I have fully migrated to nrpe.
 
I mention not using passwords as the log file is full of errors
regarding Invalid passwords
I have started disabling the SysTray on the servers -- this being
enabled was a misconfiguation.
 
Any advice gratefully appreciated.
 
Kind Regards,
 
Matthew.
