Our MobiLink sessions stop - not consistently but more regularly than we like. It seems that this occurs after an "IIS Reset" has been issued on the server running MobiLink Relay Server. Looks like it stops the "SQL Anywhere - AbInterfaceRelayServer" service (D: websites AbInterfaceRelayServer IAS_relay_server Server rshost.exe -hvSQLANYe_AbInterfaceRelayServer).

Following is the a list of events that were pulled from the "Event viewer" on the server:

2012-02-26

06:20:01 The SQL Anywhere - AbInterfaceRelayServer service was successfully sent a stop control.

06:20:03 The SQL Anywhere - AbInterfaceRelayServer service entered the stopped state.

06:20:04 The SQL Anywhere - AbInterfaceRelayServer service was successfully sent a start control.

06:20:04 The SQL Anywhere - AbInterfaceRelayServer service entered the running state.

06:20:49 IIS Reset encountered an error while stopping services, which was requested by domain account. The logged data is the status code. Since the force option is on, IIS Reset will now terminate the services' processes. This may cause SCM to report errors about the services exiting.

06:20:50 The World Wide Web Publishing Service service terminated unexpectedly. It has done this 2 time(s).

06:20:50 The IIS Admin Service service terminated unexpectedly. It has done this 2 time(s).

06:20:50 IIS kill command received from user domain account. The logged data is the status code.

06:20:50 IIS stop command received from user domain account. The logged data is the status code.

06:20:51 The IIS Admin Service service was successfully sent a start control.

06:20:52 The IIS Admin Service service entered the running state.

06:20:52 Cannot register the URL prefix 'https://*:443/' for site '836849725'. The necessary network binding may already be in use. The site has been deactivated. The data field contains the error number.

06:20:53 The World Wide Web Publishing Service service entered the running state.

06:21:15 IIS start command received from user domain account. The logged data is the status code.

NOTE - This is the time the “SQL Anywhere” relay server service stopped

Next day 2012-02-27

06:20:02 The SQL Anywhere - AbInterfaceRelayServer service was successfully sent a stop control.

06:20:22 Application popup: w3wp.exe - Application Error : The exception Integer division by zero. - (0xc0000094) occurred in the application at location 0x020a4888.

NOTE - above repeats 17 times all with 06:20:22 timestamp

06:20:22 The SQL Anywhere - AbInterfaceRelayServer service entered the stopped state.

06:20:24 The SQL Anywhere - AbInterfaceRelayServer service was successfully sent a start control.

06:20:24 The SQL Anywhere - AbInterfaceRelayServer service entered the stopped state.

06:23:11 A process serving application pool 'AbInterfaceRelayServerPool' exceeded time limits during shut down. The process id was '6980'.

NOTE - Manually entered a start to the “SQL Anywhere” service

09:00:45 The SQL Anywhere - AbInterfaceRelayServer service was successfully sent a start control.

09:00:45 The SQL Anywhere - AbInterfaceRelayServer service entered the running state.

At this point the service comes online, and all activity starts as expected. The automated restarts issued daily at 06:20 do not start the service (stays in stopped status). The manual start of the service gets things going again.

Is this a problem situation that MobiLink cannot recover from an IIS Reset? Is there anything that I can do to prevent the service from stopping after the IIS Reset is issued. Note the service is defined to automatically start.

It is a known issue that the standalone RSOE or RSOE embedded in ML server cannot surrive across a IISReset (or IIS worker recycling or killing the worker). The issue was reported on QTS683240 and fixed in 12.0.1.3436 RS. The issue had not been fixed in 11.x RS.

A workaround without a fix is to restart RSHOST together with the web service. Then we expect RSOE to recover automatically.
