Setting mutationLimit to 150 can resolve this issue, but I guess it's not a good idea 🤔

@Sleaf Do you have a repro or is your app public, so we can take a closer look? Feel free to email me billy at sentry.io

150 mutations is quite low, it shouldn't take this long to process them (from your screenshot it looks to be even fewer than that too).
