Subject Re: Array example fails for large number of numbers
Date Sat, 23 Jul 2005 01:03:21 GMT
Hi All

I am using Axis 1.6alpha ( CVS checkout ).  I am trying to run a 
modified array example (CPP:RPC) which segfaults if
numbers returned are > 209 but works for numbers > 100000. ( I think 
this may be some sort of a memory error )

I have attached the modified client and server files of the Array 
(CPP:RPC) example with the WSDL. (The rest is the files as generated by 
wsdl2ws)
The server does return all the values which is seen in the SOAP-RESPONSE.

The example works fine for all values when run under gdb.

I have also tried passing various values to setServerTimeout() and got 
the same results.

Any pointers to why this is happening and how it can be solved?

Cheers
Krishna
