While hitting the external system through SFDC (CS15.salesforce.com) getting error as "System.CalloutException: More than 20 connections opened to server" , since we are usring multiple API as SOAP and REST .
Please note --- The same setup was working earlier but from last two days all of a sudden start getting above mentioned error .
Even if i will try to trigger separatly still getting the same issue .
Any ideas for how I can understand this error message, the related limit, and suggested workarounds appreciated.
