# [FAQ] TiCDC 日志告警 "the target capture is not exist, sent the table to orphanTables"

## Key Words

hang，卡住，不同步

## Description

1. Capture 日志持续刷新 WARN 信息，```[WARN] [changefeed.go:575] ["the target capture is not exist, sent the table to orphanTables"]```。
2. Changefeed checkpoint 不推进。

## Content

1. 该 Warn 信息是在 TiCDC 的 owner 在 Capture 之间移动表时产生， TiCDC owner 先尝试从源端（Capture）删除该表，并将该表添加到目标端（Capture）。如果此时目标端处于脱机或异常状态，owner 会将这个表添加到 orphanTables 中并在日志中打印 WARN 级别的信息，并在下一次 tick 时尝试继续进行这个任务。
2. 从日志打印的内容可以发现， TiCDC owner 一直处于未删除无效 table job 的状态，所以 TiCDC owner 在每次 tick 时会将表重复添加到 orphanTables 中，进而导致其他任务无法正常推进。示例：capture-id=0d84f881-5a27-4ad8-933e-0081bd394ade 一直在进行被转移操作。
