APAR status
Closed as program error.
Error description
When the web server Plug-in receives a 503 response, it decrements the connection count TWICE. This can result in a negative value for pendingRequests.
Local fix
work-around would be to set MaxConnections to -1 for all Servers in the plugin-cfg.xml file.
Problem summary
**************************************************************** * USERS AFFECTED: IBM WebSphere Application Server webserver * * plugin users * **************************************************************** * PROBLEM DESCRIPTION: Connection counts may go negative * **************************************************************** * RECOMMENDATION: * **************************************************************** When a 503 response is received, plugin would decrement the currentconnection count twice. They could lead to the currentconnection count going negative and cause uneven load balancing.
Problem conclusion
Decrement of current connection counts corrected to only decrement once when a 503 response is received and a check was added to prevent a negative currentconnection count. The fix for this APAR is currently targeted for inclusion in fix packs 6.1.0.43, 7.0.0.23, 8.0.0.3.
