Standalone - Error during subscribing exception

I am intermittently getting the following exception (taken from the playserver log) in standalone backendless. I use the pub/sub subscription in the mobile client.

05:53:16.518 [ERROR] weborb - [WEBORB ERROR] Method invocation raised an exception. Method - public java.util.List com.backendless.services.messaging.MessagingService.pollMessages(java.lang.String,java.lang.String,java.lang.String,java.lang.String) throws java.lang.Exception.

It is hard to say what is the problem. Please try to reproduce it with online service. In other case contact sales@backendless.com to get info about standalone support.
