IBM IDS ENTRP E / 5724L2304 / B15 - IDS 11.50

This is observed only on Linux platform. 
 
IDS crashes after it runs out of OS resources. Following 
messages are logged in online.log: 
 
08:59:05  KAIO: error in kaio_WRITE, kaiocbp = 0x62a417e0, errno 
= 0 
08:59:05  fildes = 257 (gfd 4), buf = 0x0x63a36000, nbytes = 
8192, offset = 46333952 
08:59:05  KAIO: error in kaio_WRITE, kaiocbp = 0x62ed6a28, errno

* USERS AFFECTED:                                              *

* PROBLEM DESCRIPTION:                                         * 
* This is a linux specific issue. It is possible that when io  * 
* request is submitted to OS via io_submit() system call , OS  * 
* may fail to process this request due to insufficient OS      * 
* resources. So in failure case, io_submit() returns a negated * 
* error number (the negative of one of the errors , for        * 
* example -EAGAIN, -EINVAL, -EBADF etc) and no global errno is * 
* set. The failure scenarios were not being handled correctly. * 
**************************************************************** 
* RECOMMENDATION:                                              * 
* Upgrade to IDS 11.50.xC5 or above.                           *
