cannot create lock file

[Dalius Gilvydis]

I've got an interesting locking problem that I cannot figure out...

I can succesfully creat edit query PRs from the unix command 
line.  *However*, I cannot edit PRs using TkGnats or gnatsweb.  I get an 
error that says:

Cannot create lock file 
/usr/local/share/gnats/gnats-db/gnats-adm/locks/3.lock  The PR has not been 
changed. If this problem persists, please contact a GNATS administrator.

Any ideas as to what could be happening?  I am able to create and query PRs 
using tkgnats and gnatsweb, but not edit.  I am using gnats v3.113.1, 
tkgnats v.3.0.18, and gnatsweb v.2.9.0.  Any help would be appreciated...
