A technical glitch halted trading in the Australian stock market for most of the session on Monday, but other Asia markets gained ahead of central bank meetings in the U.S. and Japan later in the week.
The technical glitch delayed the Australian market open and then halted trade in the afternoon before market operator Australian Securities Exchange (ASX) said in a media statement the market would not re-open on Monday, and there would be no closing single price auction.
"ASX will advise the process for determining closing prices, remaining session states and status of orders," the statement said.
In another statement in the late afternoon, the ASX managing director and CEO, Dominic Stevens, said the glitch rose from "a hardware failure in the main database used by the system," which had a "number of knock-on consequences that affected the operation of the market."
Stevens added the issues were not related in any way to cyber security. An ASX spokesman said in the morning that the exchange was continuing to work with its technology vendor to prevent a recurrence.

Investors will look for clarity from the U.S. Federal Reserve on the timing of the next interest rate hike, with many analysts suggesting a rise in September was unlikely following a series of weaker-than-expected economic data.
The Fed's future interest rate projections, commentary from Janet Yellen and the post-Federal Open Market Committee statement will drive markets, according to Ray Attrill, global co-head of foreign exchange strategy at the National Australia Bank.
In Japan, the Bank of Japan's (BOJ) policy decision itself would carry sentiment in the market, according to Attrill, along with the release of the central bank's comprehensive review of the efficacy of its policy measures to date, which was also due.
There has been persistent uncertainty over what BOJ Governor Haruhiko Kuroda might do next.
"Our best guess - and it is frankly little more than that - is that the BOJ will elect to take measures that underpin the recent steepening of the yield curve," Attrill said, adding it could be achieved by a combination of adjusting its bond buying program and taking the policy rate deeper into negative territory.
"If they succeed in this without sending equities into a spin, it can help the cause of a (modestly) weaker yen," he added.
Both the Fed and the Bank of Japan are set to begin their two-day policy meetings on September 20.
