Large archive conversion problem

[Rangesh Kona]

Hi, I am having trouble in converting large archives ( since 1990 ). All my emails are in .txt format  on SunOS cdnemailweb.Cadence.COM 5.8 Generic_108528-19 sun4u sparc SUNW,Ultra-80   Here are my trials : 1. mhonarc –add /usr1/archives/*.txt  ( doesn’t work ) fails with Arguments too long   2. find /usr1/archives/ | xargs cat > /tmp/mbox     mhonarc –add /tmp/mbox    fails with Unable to create temp file   Too many open files error      I increased limit to 1024 using limit command    This time I will get Unable to create temp file Bad file number   3. I did a cat on all files by year / quarter ( No use still above problem )     cat on all files by year and month works but takes longer time than what I expected.      Is there any simple solution to process these large archives.   Thanks for all your help.
