Forum OpenACS Development: Very long pause in server startup after "code block procs_register" in acs-tcl/tcl/request-processor-init.tcl

Both my production and my development OACS 4.6.3/ PostgreSQL 7.2.3 instances hold this really annoying five-minute break during startup:

[01/Oct/2003:15:27:51][18005.16384][-main-] Notice: Executing initialization code block procs_register in /XXXX/packages/acs-tcl/tcl/request-processor-init.tcl
[01/Oct/2003:15:32:54][18005.16384][-main-] Notice: tcl: generating interp init script

I dug around a bit in request-processor-init.tcl, but have no idea why this is taking so long (except for nagging suspicions about nsv_[somethings]). If I set up a new OACS, startup is quick, without any pauses between those two lines in the log.

I would appreciate some ideas as to the reason of this behaviour, even though I would venture the guess that nothing can be done about it short of a new install...
