openclaw - 💡(How to fix) Fix [Bug]: Session store lock timeout causes dropped Telegram messages [3 comments, 4 participants]

• Short follow-up messages during a long-running response are most affected
• Lock appears to not be released properly or times out too quickly
• Error occurred 4x within ~40 minutes (23:02, 23:05, 23:16 twice, 23:40 UTC)
• Workaround: openclaw gateway restart clears all locks

Fix Plan

To resolve the issue of silently dropped Telegram messages due to session store lock timeouts, we will implement a queueing system for incoming messages and extend the lock timeout with a retry mechanism.

Step-by-Step Solution

1. Install a message queue library: Use a library like bull to handle message queueing.
2. Implement queueing for incoming messages:

   const Queue = require('bull');
   
   // Create a queue for incoming messages
   const messageQueue = new Queue('telegramMessages');
   
   // Process incoming messages
   telegramBot.on('message', (msg) => {
     // Add message to queue
     messageQueue.add(msg);
   });

3. Extend lock timeout and implement retry mechanism:

   // Extend lock timeout to 30 seconds
   const lockTimeout = 30000;
   
   // Implement retry mechanism with 3 attempts
   const maxAttempts = 3;
   const retryDelay = 5000; // 5 seconds
   
   // Function to acquire lock with retry
   async function acquireLockWithRetry(attempt = 0) {
     try {
       // Attempt to acquire lock
       await acquireLock();
     } catch (error) {
       if (attempt < maxAttempts) {
         // Retry after delay
         setTimeout(() => acquireLockWithRetry(attempt + 1), retryDelay);
       } else {
         // Handle max attempts reached
         console.error('Max attempts reached');
       }
     }
   }

4. Process queued messages after lock is released:

   // Process queued messages
   messageQueue.process(async (job, done) => {
     // Acquire lock with retry
     await acquireLockWithRetry();
   
     // Process message
     try {
       // Process message logic here
       done();
     } catch (error) {
       // Handle error
       done(error);
     } finally {
       // Release lock
       releaseLock();
     }
   });

Verification

To verify the fix, send a message that triggers a multi-step tool chain and then send another message while the response is being generated. The second message should be processed after the lock is released, and no errors should be logged.

Extra Tips

• Monitor the message queue length and adjust the queueing system as needed to prevent overload.
• Consider implementing a dead letter queue for messages that fail processing to prevent loss of data.
