Backup client restore fails due to Out of Memory or GC overhead limit exceeded
症状
The backup client fails during the restore due to the default Java heap space not being enough for the operation to be performed.
One of the logs below can be shown in the atlassian-stash-YYYY-MM-DD.log:

The default MaxHeapSize defined for the Java in your system is not enough for performing the restore. On the output below, for example, this value is 1GB:
$ java -XX:+PrintFlagsFinal -version | grep -iE 'HeapSize|PermSize|ThreadStackSize'
uintx AdaptivePermSizeWeight = 20 {product}
intx CompilerThreadStackSize = 0 {pd product}
uintx ErgoHeapSizeLimit = 0 {product}
uintx HeapSizePerGCThread = 87241520 {product}
uintx InitialHeapSize := 62733632 {product}
uintx LargePageHeapSizeThreshold = 134217728 {product}
uintx MaxHeapSize := 1004535808 {product}
uintx MaxPermSize = 174063616 {pd product}
uintx PermSize = 21757952 {pd product}
intx ThreadStackSize = 1024 {pd product}
intx VMThreadStackSize = 1024 {pd product}

While executing the restore, add a parameter to the restore command, increasing the heap size for that execution by passing a higher maxHeapSize parameter. For this specific example, we raised it to -Xmx2g.
According to the link above, that's how you'd normally do:
$ java -Djdbc.override=true -Djdbc.driver=org.postgresql.Driver -Djdbc.url=jdbc:postgresql://HOSTNAME:PORT/DATABASE -Djdbc.user=stashuser -Djdbc.password=password -Dstash.home="path/to/stash/home" -jar /path/to/stash-restore-client.jar /path/to/original/backup/fileChange the command below into:
$ java -Xmx2g -Djdbc.override=true -Djdbc.driver=org.postgresql.Driver -Djdbc.url=jdbc:postgresql://HOSTNAME:PORT/DATABASE -Djdbc.user=stashuser -Djdbc.password=password -Dstash.home="path/to/stash/home" -jar /path/to/stash-restore-client.jar /path/to/original/backup/file
