Hi

Apache/ColdFusion error JRun server(s) probably down

Versions:  Apache 2.2/CF 9,0,1,274733 on Solaris 5.10


We are getting a high number of transaction failures on Credit Card payment logging. These seem to be associated with an apache/CF instance connection problem - "JRun server probably down" - when in fact it seems to be up and running. This type of error is something we see quite a lot of across the board but have not linked it to a specific transaction/session failures until now.

This is the Apache error log

[Tue Nov 05 17:57:56 2013] [notice] jrApache[11037: 6765]  could not initialize

proxy for 127.0.0.1:51004

[Tue Nov 05 17:57:56 2013] [notice] jrApache[11037: 6765]  Couldn't initialize f

rom remote server, JRun server(s) probably down.

[Tue Nov 05 17:57:56 2013] [notice] jrApache[11037: 6765]  JRun will not accept

  1. request.  Check JRun web server configuration and JRun mappings on JRun server.

This is the Apache access log

- 192.168.39.1 - - [05/Nov/2013:17:57:56 +0000] "POST /print/ HTTP/1.1" 500 1043 "-" "WPM_webHTTP" 277 1280 8499

- 192.168.39.1 - - [05/Nov/2013:17:58:22 +0000] "POST /print/ HTTP/1.1" 200 187 "-" "WPM_webHTTP" 3275 378 667460


It has been suggested that we may want to try and increase the timeouts for this. Currently these are the defaults of:
#JRunConfig ConnectTimeout 15
#JRunConfig RecvTimeout 300
#JRunConfig SendTimeout 15

If this is something you would recommend what would sensible new values for this be?

Equally if you think the fix for this is something completely different let me know.
