This is probably way to much but I found that 32M was randomly failing when I generate the Nagios config files. The problem has only shown up since I added another 150 monitored hosts 3 weeks ago and since I moved MySQL I have got plenty of spare memory on the main host.</DIV> <DIV> </DIV> <DIV>Thanks,</DIV> <DIV>Simon<BR></DIV> <DIV> </DIV> <DIV> </DIV> <DIV><FONT size=1><FONT face=Verdana><STRONG><FONT color=#da130e>Simon Finch </FONT><FONT color=#808080>|</FONT></STRONG><FONT color=#808080> <STRONG>ES</STRONG></FONT><FONT color=#808080><STRONG>M Specialist</STRONG></FONT></FONT></FONT><BR><FONT color=#da130e size=1 face=Arial><FONT color=#808080><IMG alt="" src="cid:PTGVVPNQHJPQ.IMAGE.xxx" width=87 height=33></FONT></FONT></DIV> <DIV><FONT color=#da130e size=1 face=Arial><FONT color=#808080>Ground Floor, 4-16 Montgomery St, Kogarah NSW 2217</FONT></FONT></DIV> <DIV><FONT color=#da130e size=1 face=Arial><FONT color=#808080><FONT face=Wingdings>(</FONT><FONT color=#808080 size=1 face=Arial>+61 2 9952 2574 </FONT><FONT color=#808080 size=1 face="Wingdings 2">7</FONT><FONT color=#808080 size=1> </FONT><FONT color=#808080 size=1 face=Arial>+61 412 256 814</FONT></FONT></FONT></DIV> <DIV><FONT color=#da130e size=1 face=Arial><FONT color=#808080>Email: <A href="mailto:finchs@stgeorge.com.au">finchs@stgeorge.com.au</A><BR><A href="http://www.stgeorge.com.au/"><B><U><FONT color=#808080 size=1 face=Arial>www.stgeorge.com.au</FONT></U></B></A><BR>______________________________________</FONT><BR><EM>St.George Bank IT - Good with people.
