I am getting the following error as soon as I start JIRA on my Linux test system.

Java HotSpot(TM) 64-Bit Server VM warning: Failed to reserve shared memory (errno = 1)

What system or JIRA parameters to change to fix this issue ? Please advise. Thanks

Your Linux is 32 or 64 bit?

64-bit Linux.

[root@test ~]# getconf LONG_BIT
64

It's nothing to do with Jira really. That error usually means that you've tried to allocate more memory to the JVM than your system is configured to allow (either it hasn't got that much memory, or there's a quota or security limit)

Nic, How do I check, what is configured in the system ?

Read the system information page.

When you need to edit them, the memory settings are in the setenv.sh/bat

errno = 1 generally implies permission denied. 

Refer (source):  

(errno = 1)
Errno 1 is permission denied. On CentOS 6.x this is usually resolved by adding the Group ID (GID) of the server to /proc/sys/vm/hugetlb_shm_group. In your case the server runs as user dsuser and group dsuser. 

echo <numeric_gid_of_dsuser> > /proc/sys/vm/hugetlb_shm_group
