I just compiled 1.8.8rc2 and so far so good - no crashes. After that I have problem with calculated items: 2277:20110915:174822.334 Item [h069:load.per_core] became not supported: Invalid first parameter in function [last("system.cpu.load[,avg1]")] Item "load.per_core" formula looks like: 2277:20110915:174924.614 Item [h154:swap.used] became not supported: Invalid first parameter in function [last("system.swap.size[,total]")] Item "swap.used" formula looks like: 2278:20110915:174822.327 Item [d042:disk.writes.ms] became not supported: Invalid first parameter in function [last("disk.writes.time")] Item "disk.writes.ms" formula looks like: According to documentation these items looks correct and works fine with previous version 1.8.7. Is there any change in calculated item formula that makes incompatibility? |

most likely they are missing data and can not be calculated right now. they are expected to populate data a bit later then |

It seems that all calculated item in my system became 'not supported' after update do version 1.8.8rc2 from crashing 1.8.7. |

Robert, Can you please try to activate your calculated items again ? This could be done in the configuration screen of your item setting Status=Active For us seems that this issue is similar with Can you please confirm that now this issue is fixed for you ? |

Yes, I activated a few of calculated items again but they 'became not supported'. So, I suppose crashing zabbix_server issue (1.8.7) is fixed but problem with processing calculate items is another issue. |

Confirmed incorrect processing of quoted function parameters in calculates items. |

will this result in 1.8.8rc3 ? if it's a regression after 1.8.7, it might be a good idea <rudolfs> yes, that is the current plan <richlv> thanks |
