Details

In Azle, calling `setTimer` causes infinite loop of timers ### Impact Calling `setTimer` in Azle versions `0.27.0`, `0.28.0`, and `0.29.0` causes an immediate infinite loop of timers to be executed on the canister, each timer attempting to clean up the global state of the previous timer. The infinite loop will occur with any valid invocation of `setTimer`. ### Patches The problem has been fixed as of Azle version `0.30.0`. ### Workarounds If a canister is caught in this infinite loop after calling `setTimer`, the canister can be upgraded and the timers will all be cleared, thus ending the loop.
