There is no issue on AIX 5.3 but starting from AIX 6.1 onwards, there is this problem.

Any work around ?

UNIX and Linux

Unix (trademarked as the UNIX certification mark) is a very mature family of multitasking, multiuser computer operating systems that evolved from the original AT&T Unix. Unix development starting in the 1970s by legendary Bell Labs programmers Ken Thompson, Dennis Ritchie, and others. Unix was first targeted for the Bell System and AT&T licensed Unix to outside parties. In the 1970s time period, this lead to a variety of for-profit as well as not-for-profit Unix variants.
In the early days, this included the University of California, Berkeley (BSD), Microsoft (Xenix), IBM (AIX), and Sun Microsystems (Solaris). In the early 1990s, AT&T sold their Unix rights to Novell. In 1995 Novell sold their Unix business to the Santa Cruz Operation (SCO). The UNIX trademark was passed to The Open Group, a "neutral" industry consortium. The Open Group promoted the use of the UNIX trademark for certified operating systems that comply with the Single UNIX Specification (SUS). In 2014 Apple's macOS became the Unix version with the largest global install base and macOS remains the largest Unix-user base today.
Linux is a family of open source Unix-like operating systems based on the Linux kernel. The Linux kernel is an operating system kernel first released by Linus Torvalds on 17 September 1991. Linux distributions include the Linux kernel, system software and libraries. Popular free open source Linux distributions include Debian, Fedora, and Ubuntu. Commercial Linux distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise Server. Linux may be freely modified and redistributed. Anyone on the planet may create a Linux distribution for any purpose.
