I added a test of correct ns_cond behavior here: https://bitbucket.org/apiskors/naviserver/commits/2ed58b6a9c0567fe7cbee1080e30274b2aba64be
Which adds these two new files: tests/ns_cond.test tests/testserver/modules/ns_cond.tcl To run the test on Linux, just do: make test TCLTESTARGS='-file ns_cond.test' As you can see from the log output below, ns_cond works fine on AOLserver, but not on Naviserver. On Naviserver, once the worker thread calls "ns_cond wait" the first time, it just never wakes up. It's as if the cond signal just never makes it here. This was run on Linux; behavior on Windows is the same. # BUG on Naviserver, the worker never wakes up: ns_cond.test [18/Oct/2014:02:34:50][23566.2aadb6049700][-command-] Notice: tst_cond_master: New thread '' started for running tst_cond_worker.
