Need help. Unable to create threads after a certain number

Hi,

I have a process which creates pthreads to generate some reports. After creating the reports these threads return null. But after 1024 threads, the process is not able to create any threads further.,and at max 5 threads are existing simultaneously and are returning the control back after they have created the reports.

>shud i cleanup any resources explicitly if it is not being done.

>is this a normal behaviour

I thought there is only a limitation on maximum threads existing simultaneously.

Thanks in advance

NAME
dimbl - Distributed Timbl SYNOPSYS
dimbl [timbl options] [-S <num of threads>] DESCRIPTION
dimbl extends timbl with the possibility to run the classification task on multiple threads. This is done by splitting up the Instancebase in parts that are handled in parallel. Every test instance is tested against each partial Instancebase. The results are merged and then the k Nearest Neighbours are calculated. NOTES
dimbl only works for the IB1 variants of timbl. Not all timbl options are fully supported. Documentation is lacking. OPTIONS
-S <threads> run the server on 'threads' parallel threads. all timbl options are documenented in timbl(1) dimbl handles most of them in the same way as timbl except for -i filename and -I filename -I will create 'threads' Instancebase files and store their names in 'filename' together with the name of the weighting file. -i will use such a file to read back in 'threads' Instancebases for a classifying task. The -S option is ignored in that case. dimbl will use the number of files found in 'filename'. BUGS
