Description Trevin Beattie 2015-09-03 18:01:51 UTC
Description of problem:
We have a multi-threaded Java application which makes dozens of connections to the Amazon SQS web service to read messages every 15 minutes.  Occasionally -- about once a day or so now -- one of the threads will hang, preventing the application from terminating and blocking subsequent runs until we find out about it and kill the process.

After taking some Java stack dumps while hung and some research we found that the Apache httpclient library had a bug where the socket timeout was ignored during the SSL handshake:


This was reportedly fixed in version 4.3.6 of httpcomponents-client, but RHEL6 only has commons-httpclient 3.1 which is no longer supported.  I don't see anything showing whether the fix was backported to the older library.

Version-Release number of selected component (if applicable):

How reproducible:
Low -- roughly 0.03% probability

Steps to Reproduce:
1. Create a MultiThreadedHttpConnectionManager.
2. getConnectionWithTimeout (e.g. 60 seconds)
3. In the HttpConnectionParams, setConnectionTimeout(60 seconds), setSoTimeout(60 seconds), setBooleanParameter(STALE_CONNECTION_CHECK, true)
4. Create a TransparentPostMethod and fill it in with the required parameters for an Amazon SQS request.  Use the AWSUtils library to sign the request.
5. Open a connection, then execute the request.

Actual results:
Thread has a small chance of hanging indefinitely in the following call (jstack dump):

I’ve applied the patch locally and gave it a smoke test in our QA environment; we pushing it to production this afternoon.  We should know in a few days whether it was effective.

Comment 8 Trevin Beattie 2015-09-18 23:31:43 UTC
The patched library has been in production for a week now, and our application has not hanged at all during that time.  We're very happy with the result.  Thank you for the quick response.

Comment 9 Mikolaj Izdebski 2019-06-27 12:46:13 UTC
Red Hat Enterprise Linux 6 reached end of Maintenance Support 1 phase. Therefore this vulnerability, due to low severity, is not going to be fixed. I'm closing this bug as NEXTRELEASE as the problem is already fixed in Red Hat Enterprise Linux 8.
