A possible problem for PHP 4.3.0+MSession 1.21

Dear Lady/Sir : I can not find any technical contact in Mohawk's web but this mailling list in the internet. I am looking for solutions. If this e-mail bothers you, I appologize. I found a possible msession problem in V1.21 only, which is based upon phoenix-R1_2_030117E (PHP 4.3.0, RedHat 7.2). It looks like : 1. The PHP+msession runs slow as the listener threads increased. The PHP msession_get( ) will take more than 100ms as the listerner threads is increased to 30. This slowness will be triggered only from PHP+msession, and that is started after a few executions (say, usually after 10 times). The non-PHP msession-related programs do not trigger this slowness and works good. However, this situation and the same PHP+msession_get program does not re-create the same slowness on PHP 4.3.0+msession 1.0. 2. As soon as the slowness appears, any msession programs (including ./tools/list ...) slows down too, until the msessiond is re-booted. Anybody has the same problem or solutions ?
