Problem in Sun E450

2007-12-24 20:44:00

Dear All,
We are facing a severe problem in our Sun E450 (2 cpu, 2GB RAM,
8GB swap) running Netscape Directory server 4.15. After starting the
directory server, the listening process, slapd, starts growing & almost
consumes 2GB and stops responding. The pmap output has following lines.

Address Kbytes Resident Shared Private Permissions Mapped File
00156000 986000 985760 - 985760 read/write/exec [ heap ]

total Kb 1731728 1477288 1336 1475952

The truss ouput has following lines.

Has anyone of you experinced this problem in context with Netscape or otherwise. Is it a resource problem. Pl. give your valuable suggestions.

Thanks & regards,
