problem:  daily, in evening or morning hours, usa time, our cold fusion sites found down (4 sites, plus default admin, cf instances) connected through iis , cold fusion sites configured run windows service. 

 

resolution:  start sites via jrun.exe or start them via windows services (services.msc) , works fine, no further issues until next problem occurs again later.

 

system: 
windows 2008 enterprise 64bit
vmware client running on vmhost - host info:  vmware esxi 5.1.0 64bit, 1 cpu, 2 cores assigned.  6gb of ram.  vmware host reports less 50% cpu usage , memory across multiple vm clients (guests), no spikes of note.
cold fusion 9 64bit

version  9,0,1,274733   
edition  enterprise   
operating system  windows server 2008

environment:  dev/test server, small team of users

 

users starting service/sites via jrun, have admin rights on server.

 

storage configured san, f:\ drive on server (17gb of 300gb free).  no known processes running @ time.  windows security, application, system, , setup logs show 1 error:

"the description event id 0 source coldfusion 9 odbc server cannot found. either component raises event not installed on local computer or installation corrupted. can install or repair component on local computer.

if event originated on computer, display information had saved event.

the following information included event:

anyone have thoughts can try or how can track see happening when occurs (other physically watching happen) or if there known issue haven't found?

 

thanks much,

 

db

hi dean,

 

perhaps there useful information in cf logs.

 

[cf]\runtime\logs server or [jrun]\logs multiserver coldfusion-event.log & coldfusion-out.log

check -

•java.lang.outofmemoryerror: gc overhead limit exceeded

•java.lang.outofmemoryerror: java heap space

•java.lang.outofmemoryerror: permgen

•java.lang.stackoverflowerror:

•java.lang.outofmemoryerror: out of swap space

 

 

cf9.0.1 perhaps java 6 in use? cf9 update levels (9.0.1 being 1 best recall) officially

supports java 7. might not of upgrade change eol java 6 eol java 7 help.

as recall cf9 not support current java 8.

 

 

hth, carl.
