Hi lmtiyaz,

You may attempt to use the following code sample to avoid encountering this limit, particularly if the batch is executed in a scheduled class.
  • Count how many current jobs are being executed.
  • This information is stored in the AsyncApexJob table.
  • Before calling the Database.executebatch() method within a scheduled class, you should try something like:
  • check if there are 5 active batch jobs
  • In some cases, might need to add "Status='Queued' " to the criteria
if ([SELECT count() FROM AsyncApexJob WHERE JobType='BatchApex' AND (Status = 'Processing' OR Status = 'Preparing')] < 5){ 
   Database.executeBatch(batchClassInstance);
} else {
   //schedule this same schedulable class again in 30 mins
   nameOfYourSchedulableClass sc = new nameOfYourSchedulableClass();
   Datetime dt = Datetime.now().addMinutes(30);  // i.e. 30 mins
   String timeForScheduler = dt.format('s m H d M \'?\' yyyy');
   Id schedId = System.Schedule('MatrixRetry'+timeForScheduler,timeForScheduler,sc);
}
  • In the same 'else' clause you can send an e-mail to yourselves so you're notified that the job will run a bit later than normal.

Note: You can have more than 5 scheduled classes that will call Database.executeBatch() in a Queued status
