Description (last modified by westram) ¶
Under some conditions the progress bar shown by arb applications does overflow its estimated maximum.
If the overflow is >5% of that maximum, arb will display a warning like:
Warning: progress indicator overflow ...
If you encounter this message, please note this is a warning only.
Estimation of leftover runtime will most likely be incorrect.
Normally will not affect the result of the performed calculation.
Please follow the instructions and submit the information we need to fix the problem. Thank you
Tracking down the reasons for such an overflow is quite tricky: it works well in DEBUG version, but is known/expected to occur with calculations running very long, which may not be reproduced in reasonable time when using DEBUG mode.
Therefore starting with r17942, arb tries to log some details onto the console (i.e. into session log), which may be helpful to track down the cause of such overflows.
Overflow detection was introduced to trunk with r17260.
Known reasons why overflow may occur:
- integer overflow in estimation of overall steps (most likely unsigned; signed overflow causes a different message).
- unexpected child progress-counters cause too many implicit counter increments
- …?
Fixed overflows:
parsimony quick add (was: ~14000 species, strong filtering → warnings)- got detailed logs (ty jan)
⇒ detected overflow (e.g. insert 9964 intoof 108199).
fixed by [19510].
- got detailed logs (ty jan)
Known but not yet fixed occurrences of such overflows:
- [none]
