aix 421+ nv51 + nway 122 on 43p,512m,1 giga ps, df is ok .
 Every once in a while NV gui disappear on us and a core dump is
 created (not in /usr/OV/PD ... but in user home directory )
 We can not recreate the problem and it is unpredictable .
The last time it happened , the core showed
/usr/CML/bin/nwsstatif
and the other time it was ovw_binary .
I can not recreate the problem , it happens once a day .
The last time it occured was when I was working with ipmap .
Did not see anything in errpt ,
The problem is only with NV gui , the dtterm were ok .
Did any body experience it ?
 Thanks Dror
